Yes wondering this as well. Cannot find the chapter 1 anywhere
the first chapter is called "regret of the sea" idk if it's on mangago but it essentially shows the guy's confession he talked about in chapter 2 and also the white (?) haired guy discovering that his childhood friend isn't homophobic and he was manipulated to reject the confession. So, as the title says, he regrets everything, realizes he still has feelings and apologizes to the guy he rejected. We then see the kiss between the two (that is also in ch.2) but he gets rejected and goes to the beach to cry (the sea part of the title)
(very shortened)
Sorry if my story telling created any confusion lol
oh btw the white haired guy is a victim but not that much, as soon as he saw them kissing he started asking private and personal questions (do men take it up the ass? are you the top or the bottom? when you confessed did you want me to put it in your ass?) and stuff like that
with chapter 2 where is the first chapter?
